This thesis investigates the importance and significance of thermally excited 630.0 nm emissions in the cusp and polar ionosphere. Thermal excitation by heated ambient electrons in the cusp and polar ionosphere is a rarely ...
• #### Thermodynamic and Kinetic Modeling of CH4/CO2 Hydrates Phase transitions ﻿

(Peer reviewed; Journal article, 2013)
Natural gas hydrates in reservoirs are thermodynamically unstable due to exposure to mineral surfaces and possibly undersaturated phases of water and hydrate formers. Changes in global temperatures also alter the stability ...

(Peer reviewed; Journal article, 2019)
Using 3‐D particle‐in‐cell simulations, we study magnetic reconnection with the X‐line being spatially confined in the current direction. We include thick current layers to prevent reconnection at two ends of a thin current ...
